Dynamic Sound Positioning: Tales of Audio in the Third Dimension,

Audio, Lecture

Scott Selfon
Xbox Senior Audio Specialist, Microsoft
While the creation of multichannel scores and ambiences has become increasingly common, perhaps the most important element of 5.1 implementation is the use of 3D-positioning. After covering some of the basic concepts of 3D, including distance-based attenuation and panning, the topics move into newer techniques that allow for more immersive 3D positioning: distance-based filtering, directional sound sources, the positioning of multichannel source material, and reverberation simulation. Prioritization and culling techniques for positioned sound sources are also discussed.

A better understanding of how various 3D spatial simulation models work, as well as an introduction to multichannel-designed 3D positioning. An early look at some next-generation 3D library features and techniques.

This talk is designed for sound designers and audio programmers of all levels. Basic positioning technique is covered prior to moving into more advanced topics for next-generation audio implementations.
